Don't know much about sink holes in Florida, but other siblings have shown the cleaned bottom slab of the building thoroughly cleaned of rubble. I believe evidence of a sink hole would be visible.

Looking for more videos a just ran across this one.....about 3 minutes he mentions no sink hole evidence
Step, none of these guys talk about factor of safety in design, it has been a long time since my design courses but most buildings these days are designed to a factor of safety of about 2, right?
Gebees SLUPSU, all designs steel, concrete, retaining walls, etc. All have a great design safety factor within their empirical design methods. 1980, don't know if allowable stress design was employed or the now common strength method. Never the less whatever the design method used at that time doesn't appear to be the cause of the failure....
Providing:
The design was performed in accordance with ACI practices at the time, which I'm sure it was, but latest info comming indicates maybe the specifications were a little weak in comparison to current specs....of course, doesn't take a structural guy to realize that the building had maintenance structural issues that needed to be addressed.
Given time, we will all know the cause of the Surfside collapse, or a fabrication there off....
Collapsed Surfside Towers Actually Broke Building Code From the Very Beginning

Thank you manatree,
Very good article. I read an article last month that the general contractor quit about six months into construction due to numerous design changes during construction.
I thought it was a good cliff notes version of what is known so far. To me, this paragraph is key.
Another building in Miami has issues and has been evacuated.

‘They Were Bullies’: Inside the Turbulent Origins of the Collapsed Florida Condo
The team that developed Champlain Towers managed to build the condos despite checkered pasts, internal strife and a last-minute change that infuriated leaders in Surfside, Fla.

While a lions share of the blame lies with the developers & builders,it appears that the local government officials were at best ill equipped to do their jobs. At worst, negligent or corrupt. Delegating the building inspections to the builders? Seriously?!?! Shoot, I’d have a PhD if I was allowed to grade my work myself.

Add water/corrosion issues with a bad design, bad construction and lack of oversight and you get a catastrophic building collapse. Simply no excuse that this can happen. I'm not sure how the more recent structural reviews didn't catch the design issues unless it's not as much a design issue as a construction/material issue.
Found this video by Josh Porter (building integrity). I like his presentations, makes the engineering mechanics in his discussions more palatable for public consumption.Sorry about that link, try this one below and scroll down to the file called "structural-plans," the one that's 9 MB's in size. There isn't a detail specific to that column, I suppose the approved shop drawings would have worked out the details beyond the contract documents. Lot's of other documents at the link.

Watched 1/2 the video, will continue another time.
